Just Having Fun with USPI proof half centavos - The Number One Finest Set of All Time

About this set: There are just five coins in this series, but it's fun and hard anyway, especially in nice, cherry red.
The key date is the 1905. My gosh, PCGS has only graded 3 1905 proofs gem red. Can you imagine how rare that is? There's nothing like it in the US series.
The 1904 is just a milli-snitch easier, with 4 in gem red. And the 1903 is the easiest.
But despite the scarcity the coins are not yet expensive, IF you can find them. You should be able to put together a nice set in proof 65 gem red for under $10,000
